Description

Gasification Melting Furnace And Treating Method For Combustible Material Using The same}

The present invention relates to a gasification furnace, and more particularly, to a gasification furnace used for treating and energizing combustible materials including waste.

The reaction of converting flammable waste into energy can be classified into incineration (combustion) in an oxygen-rich atmosphere and gasification in a low-oxygen atmosphere. Most wastes are produced by incineration to generate hot flue gases and steam recovery from the waste heat of the flue gases.In the process of incineration, heavy air pollutants (SOx, NOx, dioxin, etc.) and heavy metals are charged in amounts of 10 to 20%. The incineration ash that is eluted and needs to be landfilled is generated, and the waste treatment technology through gasification that is an alternative to the energy utilization of steam is being considered.

In general, gasification refers to a process in which substances that can be converted into a gaseous phase such as carbon, hydrogen, and oxygen in a combustible material are converted to carbon monoxide, hydrogen, water, and hydrocarbons in a reducing atmosphere of less than 600 degrees of oxygen. At 1000 ° C and above, these materials are further pyrolyzed to convert to carbon monoxide and hydrogen. The gasification reaction is an endothermic reaction, and a heat source must be supplied to the outside to some extent, and this heat source has a characteristic that the gasification reaction proceeds with heat generated as a part of the synthesis gas is further oxidized to carbon dioxide. Accordingly, even when gasified, some of the carbon dioxide is contained in the exhaust gas, and the heat generated when the carbon dioxide is generated means that it is used as an endothermic reaction for gasification. In the case of gasification reaction, it is possible to suppress the generation of air pollutants (SOx, NOx, dioxin) generated by the oxidation reaction, and to produce power more efficiently than steam, such as gas engine / turbine power generation, or hydrogen and ethanol, etc. Synthetic gas that can be converted into fuel is obtained, and there is an advantage that the non-combustible components included in the combustible material can be converted into slag on the glass instead of ash through high temperature gasification.

However, in most gasification reactions developed to date, the enthalpy required for gasification reaction has a great difficulty in stably supplying part of the input due to the uniformity of the input and the characteristics of the waste with low calories. In addition, the thermal equilibrium temperature of the gasification temperature is also formed low, so that it is very difficult to stably obtain a high temperature of 1000 ° C or higher. In addition, the likelihood that a lot of unburned or undecomposed pollutants are discharged in the exhaust gas. In addition, the ash is not slag, because the temperature is low.

Efforts have been made to apply plasma torches to waste treatment and energy for complete disposal of waste, slag conversion of ash and stable provision of high temperature conditions. Many developments have been made for plasma gasification melting furnaces that melt / gasify waste with energy supplied from thousands of degrees of plasma torch, convert nonflammables into slag, and convert flammables into syngas. In particular, efforts have been made to improve energy efficiency while minimizing the amount of power input to plasma.

In general plasma gasification melting, the plasma mainly plays a role of raising the temperature for the cleaning of unburned carbon and hydrocarbons in the synthesis gas after melting or non-combustible materials such as metal and ash. In addition, the conventional plasma gasification melting furnace is most commonly a straight shaft furnace in the vertical direction, the waste is injected from the top of the shaft to the lower end where the melting reaction occurs, a plurality of plasma torch is installed at the lower end of the shaft Has a structure. The plasma torch serves to melt the waste moving toward the lower surface of the melt. In addition, a high-calorie fuel such as coke is additionally supplied so that a stable gasification reaction occurs. Melt formed by the melt is formed on the bottom of the melt, and the synthesis gas rises to the top of the melt and is discharged out of the melt.

Since the conventional plasma gasification melting furnace has a straight structure in the vertical direction, melting and gasification proceeds stably only when the waste introduced into the melting portion continuously moves toward the bottom of the melting portion at a constant speed, but it is easy to adjust the movement speed of the waste. not. In addition, when a change in the moving speed of the waste toward the bottom of the melt portion may cause problems in the processing speed, melting and gasification of the waste. In particular, when the input amount of the waste is large, the contact of the waste and the gas may not be efficiently performed, which may cause a problem of slowing the reaction rate.

In addition, the conventional plasma gasification melting furnace occurs a melting reaction at 1600 degrees, but the gasification temperature is much lower than 1200 ℃, the temperature at which the synthesis gas is discharged below 1000 ℃. Because of this, several percent of hydrocarbons and tar are included in the syngas, and there is also the possibility of dioxin resynthesis in the subsequent process. Therefore, the high temperature synthesis gas is immediately cooled at the rear end to suppress the generation of pollutants, resulting in a problem of low energy efficiency. In addition, the synthesis gas purification process of the subsequent stage is carried out in a multi-stage complex configuration can be excessive. Currently, to solve this problem, the synthesis gas is cleaned again by raising the temperature with plasma, but the overall efficiency is lowered.

That is, a plurality of first oxidant inlet 15 may be installed according to the diameter of the gasification unit 10.

The second oxidant inlet 15 may be preferably introduced into the gasifier 10 to be deviated from the central axis of the gasifier 10 to facilitate the turning of the oxidant. The reason for introducing the oxidant in this way is to allow the partial gas reaction with the syngas that has moved to the gasifier 10 to occur stably.

In addition, if necessary, the gasification unit 10 may be provided with a pilot burner together to maintain the ignition and combustion state of the synthesis gas 53 near the position of the second oxidant inlet 15.

At this time, the second oxidant inlet 15 is preferably installed at a constant angle with respect to the center so that the injected gas is rotated. By doing so, it is possible to extend the residence time in the unburned gasifier 14 and reduce the exit from the gasifier 14. The total amount of the oxidant is preferably maintained at 50 to 70% of the amount of the oxidant required for stoichiometric combustion while satisfying the condition for maintaining the temperature of the gasifier 14 at 1200 ° C or higher.
